You're welcome Bruce. Happy New Year to you too.

And just in case you prefer the 727-100/200 tire smoke -, it's touchdown=cs727_tchdwn, 1 - but you probably already figured that out. :)

Using the 727 tire smoke:

[EFFECTS]
wake=fx_wake
water=fx_spray
dirt=fx_tchdrt
concrete=fx_sparks
touchdown=cs727_tchdwn, 1
startup=cs737_engstart

Sorry that I forgot to add that to my first reply.  ;)
